Time: 09:30-12:30

Target Audience Skill Level:
Digital forensics and cyber-investigation data professionals, including practitioners and tool developers of all experience levels.

Learning Outcomes:
At the end of this workshop you should be able to:
● Be familiar with the cyber and forensics domain concepts covered in CASE and UCO.
● Know where to find the CASE and UCO ontologies and supporting framework tools.
● Understand the process for implementing CASE with specific digital investigations tools.
● Have an introduction to the CASE Community and members that support CASE adoption efforts.

Abstract:

The CASE Community is an international consortium with members from for-profit, academic, government and law enforcement, and non-profit organizations, which has created a new specification for the exchange of standardized cyber-investigation data between tools, systems, and organizations. The open-source Cyber-investigation Analysis Standard Expression (CASE) is a community-developed ontology designed to serve as a standard for interchange, interoperability, and analysis of investigative information in a broad range of cyber-investigation domains, including digital forensic science, incident response, counter-terrorism, criminal justice, forensic intelligence, and situational awareness. The CASE Workshop at DFRWS EU 2020 will begin with an update about the growing CASE community and its progress on the new version of CASE, and proceed through practical applications of CASE, including examples. Presenters will explain the CASE adoption process and offer a demonstration of mapping the data model for a forensic tool to the CASE ontology. This session builds on the CASE Workshop presented at DFRWS EU 2019, but newcomers are encouraged to attend and participate.
